>>If you start them separately in Windows they should not be visible to each other. However, (correct me if I am wrong) they will be using the just one instance of runtime library. IF I am not mistaken, I think I have seen something on UT long ago about possible conflicts between two apps even if they run this way. I was not able to find that message, but somebody might remember.

Yep, multiple FPW apps would run in the same address space. Each instance of VFP runs in its own.
